Precision Viticulture International Home

   Welcome to Precision Viticulture International (PVI).
   Home of the Grape's-Eye View Temperature Model.
   At PVI, we believe fine wines are born of fine grapes. That's why we
   provide advanced vineyard microclimate analysis to grow the finest
   grapes for the finest wines.

   Our Grape's -Eye View Model "sees" the world from the perspective of
   grapes, blending expert science methods and practical vineyard
   experience. We help viticulturalists optimize vineyard performance,
   maximizing quality while minimizing risk and environmental impacts.
   The result is quality assurance through better wine and greater
   revenues.

PVI has pioneered the use of hemispherical photography to
analyze grapevine canopy structure and estimate incoming
solar radiation (insolation).

October 13, 2006, San Francisco Chronicle, "Vintners learn from
butterflies", by Carl T. Hall on the Friday Wine page, highlighting
applications of viticulture work by PVI's Chief Scientist Stuart B. Weiss
on microclimate. The same methodology used to understand habitat
needs of threatened Bay Checkerspot Butterflies can be applied to
measure and manage temperature regimes of grapes as they ripen.

May/June 2003, Precision Viticulture International's principals Stuart B.
Weiss, David C. Luth, and B. Guerra published "Potential solar radiation
in a VSP trellis at 38°N latitude" in Practical Winery and Vineyard.

PVI uses a precision viticulture approach, which applies
appropriate vineyard management practices according to
variation in environmental factors (soil, topography,
microclimate, etc.).
